Created attachment 7750

reduced test case for sparc

The attached files cause the following problem when compiling for Sparc: 

int64_t llvm::MachineFrameInfo::getObjectOffset(int) const: Assertion
`unsigned(ObjectIdx+NumFixedObjects) < Objects.size() && "Invalid Object Idx!"'

The reduced test case is attached.

The attached .i file also seem to causes  problems for sparcv9, xcore, hexagon
and mblaze when compiled with clang. I'm not sure if they are all related.
